, such as soy, legumes, and seeds, and other plant products.
1. Many animal proteins are high in fat content. Eating a protein rich diet can be a good thing, but it can also be a very bad thing. Many animal products have a high fat content that can contribute to future health problems. This includes heart disease, blood pressure issues, and even insulin resistance.

Animal protein is also associated with positive health effects, despite often being portrayed as unhealthy compared to plant protein (26). The Nurses’ Health study reported that poultry, fish and low-fat dairy were associated with a lower risk of heart disease (27).
Many animal products have a high fat content that can contribute to future health problems. This includes heart disease, blood pressure issues, and even insulin resistance. Of course this typically comes when animal proteins are enjoyed in excess, but when was the last time someone at a 3 ounce steak, which is the recommended serving size?
What is the effect of animal protein on cancer?
Animal Protein and IGF-1 (increased cancer risk) When we ingest proteins that have a higher proportion of the essential amino acids (which is a characteristic of animal protein), it results in our bodies producing higher levels of the hormone insulin-like growth factor-1 (IG F-1). 2-8. This hormone stimulates cell division …
Animal Protein and Cholesterol. Most animal foods contain saturated fat and cholesterol (this is true for even so-called “lean” meats like chicken, turkey, and salmon, regardless of how they are cooked or prepared—even if boiled, baked, or steamed).
4. Animal Protein and Phosphorus. Animal protein contains high levels of phosphorus. And when we consume high amounts of phosphorus, one of the ways our bodies normalize the level of phosphorus is with a hormone called fibroblast growth factor 23 (FGF23). FGF23 has been found to be harmful to our blood vessels.
High fiber intake is associated with decreased cancer risk, specifically colon and breast cancers, as well as lower risk of ulcerative colitis, Crohn’s disease, constipation and diverticulitis. It may also reduce the risk of stroke, high cholesterol, and heart disease. 40,41. 2. Animal Protein and IGF-1 (increased cancer risk)
Many people, in their effort to “get enough” protein, tend to eat large amounts of animal foods, which displaces plant foods that have these important nutrients. Fiber deficiencies, in particular, are far more common than not.
Animal Protein and Fiber (or total lack thereof) Unlike plant protein, which comes packaged with fiber, antioxidants, and phytonutrients, animal protein comes with exactly none of the foregoing. To this point, meat, eggs, poultry, dairy, fish and other animal foods have absolutely no fiber whatsoever.
Animal proteins also have , in general , higher concentrations of sulfur-containing amino acids, which can induce a subtle state of acidosis when metabolized. 18 One of the mechanisms our bodies use to compensate for this acidosis is leaching calcium from our bones to help neutralize the increased acidity. Over time, this can have a detrimental effect on bone health. 19-24
Why do we need proteins?
Our bodies use proteins from food to build and repair tissues, as well as make hormones, enzymes, and other things that are vital to our health. Read: Q&A: Vitamins and Supplements. Traditionally, meat has been thought of as our main source of protein, but there are plenty of diverse protein sources out there.
Cramer: Whey protein is a popular dietary protein supplement and one of the main proteins found in dairy products; it’ s a byproduct of cheese manufacturing.
Soybeans are one of the only vegetable foods that contain all 9 essential amino acids. They are also a good source of fiber, iron, calcium, zinc, and B vitamins. Eating soy protein in place of animal protein has been found to reduce bad cholesterol and triglycerides, which are linked to heart disease.
Cramer: The human body needs 20 different amino acids. Our bodies create 11 of them (these are called “non-essential amino acids”), but we must get the other 9 from food (essential amino acids).
Whey is also used in some infant formulas to help reduce colic and in supplements because it is believed to benefit exercise performance.
Plant protein. Found in: beans, legumes, nuts, seeds, quinoa, leafy greens such as broccoli and kale, whole grains. Cramer: Certain plants can be excellent sources of protein, often with fewer calories and fewer potentially harmful effects than animal products.
Others are missing some amino acids, so it is important to eat a variety of foods to get all 9. Studies show that people on vegetarian or vegan diets (which often rely on plant protein) are at a lower risk of certain diseases including cancers, type 2 diabetes , hypertension, obesity, and ischemic heart disease.
